Abstract The off‐stoichiometric Ni2MnGa Heusler alloy is a magnetic shape‐memory alloy
capable of reversible magnetic‐field‐induced strains (MFIS). These are generated by twin …

Ferromagnetic shape memory alloys (FSMA) constitute a subgroup of shape memory alloys
(SMA) that also exhibit a ferromagnetic behavior. Due to the unique combination of large …

The huge strains that Ni–Mn–Ga magnetic shape memory alloys can achieve are usually
described in a tetragonal unit cell approximation of a five-layered modulated (10M) crystal …

Magnetic shape memory alloys exhibit various multifunctional properties, which range from
high stroke actuation and magnetocaloric refrigeration to thermomagnetic energy …

The magnetic shape memory effect can be classified as an example of the multiferroic effect
combining ferro-elasticity and (ferro) magnetism. After short overview of all known effects the …

By introducing smart materials in micro systems technologies, novel smart microactuators
and sensors are currently being developed, eg, for mobile, wearable, and implantable …

During the last decades micro electro mechanical systems (MEMS) have been subject to
intensive research. In many cases active components, eg, for regulating fluid flow or …

Elastocaloric cooling technology has obtained huge attraction over vapor compression
systems because it is more efficient with negligible environmental impact. The elastocaloric …

Giant magnetically induced strain up to 50 times larger compared to the strain of giant
magnetostriction was observed in some Heusler alloys, particularly in Ni–Mn–Ga. In analogy …

In order to use the magnetic shape memory alloy Ni–Mn–Ga with its high achievable strain
of up to 10% for microactuators, freestanding epitaxial films are required. Here we show that …
